Quantum Epitaxial Devices Ltd. is a spin out company from Lancaster University Physics Department. QED has expertise in the development of mid-infrared LEDs, lasers and photodetectors. These are key components for gas sensor and process monitoring instrument manufacturers and their users.

The mid-infrared spectral region is of enormous interest as the practical realisation of optoelectronic devices operating in the 2-10 µm wavelength range offers potential applications in a wide variety of areas.

Applications for Mid-infrared Optoelectronics

• Optical gas sensors

• Environmental monitoring

• Industrial process control

• Spectroscopy

• Thermal imaging

• Bio-medical diagnostics

• Free space optical communications

• Military - infrared countermeasures

• Homeland Security

• Thermo-photovoltaics

We are a UK source of mid-infrared components
for use in the next generation of infrared gas sensor instruments
and many other applications

The atmospheric transmission window between 3 µm and 5 µm is well suited to free space optical communications and thermal imaging applications in both civil and military situations as well as the development of infrared countermeasures for homeland security.
